E-WASTE MANAGEMENT: E-WASTE MANAGEMENT Prepared by :- Ms. Monu Malik B.Tech (Instrumentation & Control) Roll No. 1202320 CONTENTS: CONTENTS Introduction to E - Waste Root of the Problem Indian Scenario Managing E – Waste E – Wastes : Constituents and Consequences Role of the Govt. Responsibility of Industries Role of Citizen INTRODUCTION : INTRODUCTION E – Waste means the Electronic - Waste or the electronic products nearing the end of their useful life. It includes:- Discarded Computers , Mobiles TV’s , VCR’s , Stereos Walkman’s , Copiers , Fax – Machines Electric lamps , Audio Equipments & Batteries etc. ROOT OF THE PROBLEM: ROOT OF THE PROBLEM These electronic equipments contain toxic elements like:- Lead Mercury Cadmium & Arsenic etc. which pose severe threats to man-kind. PowerPoint Presentation: It is very hard to believe that even small quantities of lead can cause brain damage in babies and other diseases related to nervous system , kidneys and blood system. INDIAN SCENARIO: INDIAN SCENARIO A recent investigation has revealed that toxic wastes of the affluent nations are flooding the world’s poorest nations without considering environment’s or worker’s health and safety . PowerPoint Presentation: The major reasons behind such exports are :- Cheap Labor Lack of environmental awareness Unemployment Lack of occupational standards And as a result , this waste is disposed in poor countries and India is one of them. PowerPoint Presentation: It is estimated that 75% of the electronic waste lie unattended in the store-houses , offices etc. and later on they get mixed with household wastes and disposed as landfills , creating environmental pollution and dangers to human life. MANAGING E - WASTE: MANAGING E - WASTE Having discussed the meaning , problem , and need for e - waste mgmt. , we can now shift our focus upon the ways and strategies that can be adopted for managing this “dormant volcano”, named e – waste. PowerPoint Presentation: It has also been seen that maximum electronic waste is generated by Industries and to manage this , certain techniques have been given which are:- Inventory Management. Productive - Process modification Volume Reduction Recovery and Reuse 1) INVENTORY MANAGEMENT: 1) INVENTORY MANAGEMENT It includes following points :- Proper control over the material used in the manufacturing process. All materials be approved prior to purchase and the material should be evaluated. Ensure that only the needed quantity is ordered. 2) PRODUCTION PROCESS MODIFICATION: 2) PRODUCTION PROCESS MODIFICATION It includes modifying the process of production which can be achieved :- By changing the materials used to make the product i.e by using alternative less toxic materials. By ensuring efficient use of the input materials i.e more output by less input. 3) VOLUME REDUCTION: 3) VOLUME REDUCTION It includes those techniques that removes toxic portion from the non-toxic wastes , reducing the volume of the waste and thus easing the disposal . Metals can be extracted and can be recycled by using techniques :- Gravity Vacuum Filtration and Reverse Osmosis 4) RECOVERY AND REUSE: 4) RECOVERY AND REUSE This technique includes recovery of the waste material which can be recovered by on site or at off site or through inter-industrial exchange . So, this method can eliminate waste disposal costs and recovered material can be reused. E –WASTES : CONSTITUENTS AND CONSEQUENCES: E –WASTES : CONSTITUENTS AND CONSEQUENCES Sources of E - Waste Constituent Consequences Solder(Circuits ) , Glass Panels & Gaskets (Comp.) Lead Damage to CNS , Blood System and kidneys. Chips & Semi - Conductors Cadmium Accumulation in Kidney and causing Liver damage. Relays & Circuit Boards Mercury Respiratory & Skin ailments. Galvanized Plates Hexavalent Chromium Asthmatic Bronchitis and DNA damage. Cabling & Computer Housing PVC Reproductive Problems , Immune System damage. ROLE OF THE GOVT.: ROLE OF THE GOVT. Responsible regulatory agencies should be set up. Adequate laws regarding E – Waste mgmt. Is the responsibility of Govt. Existing Laws should be revamped. Encouragement to Research & Development activities to find new ways to manage E – Waste. Proper support to NGO’s. Strict penalties against law breakers and outsiders who dump waste in our country. RESPONSIBILITY OF INDUSTRIES: RESPONSIBILITY OF INDUSTRIES Generators of E – Waste should provide management option. Personnel involved in managing E – waste should be properly qualified and well trained. Labeled material should be used. Create computer components of bio-degradable material. Awareness should be spread among consumers regarding threats posed by their products. ROLE OF CITIZEN: ROLE OF CITIZEN To prevent waste , electronics can be donated to low income families , schools etc. who can ill afford to buy them. E – Waste should never be disposed with household wastes instead they should be segregated. NGO’s should adopt a participatory approach with the help of we , the people. While buying e – products , care should be taken if they are made of toxic substances. CONCLUSION: CONCLUSION E – waste has reached critical proportions in the west , leading to stronger laws. This is still to be done in our country where there is no strong agency to combat e – waste tide . With the estimated number of PC’s in India touching up to 80 million by 2008 its high time we plan for the mgmt. and prevention of this tide well in advance. PowerPoint Presentation: REMEMBER THAT E – WASTE HAS TO BE PREVENTED RATHER THAN MANAGED.
